YENTILATING SYSTEM FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent No. 588,969, dated August31, 1897. Application filed June 1,1896. Serial No. 593.822. (No model.)

To altwhom it may concern:

Be it known that I, GEORGE T. FINAGIN,Of the city of St. Louis, State ofMissouri, have invented certain new. and. useful Improvements inVentilating Systems for Buildings, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part hereof.

My invention relates to a ventilating system for buildings; and itconsists in the novel construction, combination, and arrangement ofparts hereinafter shown, described, and claimed.

Figure 1 is a vertical sectional view illustrating the application of myimproved ventilating system as applied to a building. Fig. 2 is a viewin elevation showing the front of the receiving-funnel and the rear ofthe discharge-funnel. Fig. 3 is a View in elevation showing the rear ofthe receiving-funnel and the front of the discharge-funnel. Fig. 4 is ahorizontal sectional view on the indicated line 4 4 of Fig. 1. tail viewof the lower end of one of the discharge-pipes.

In the construction of my improved ventilating system I employ thevertical pipes 1 and 2, arranged side by side. The pipe 1 is aninlet-pipe and the pipe 2 is an outlet-pipe, and they pass from theupper part of the lower room to be ventilated to a position somewhatabove the roof of the building. be rectangular, circular, or of anydesired shape in cross-section.

The upper end of the pipe 1 is partially closed by a cover 3, and asection of tubular pipe 4 is inserted through said cover 3 to form abearing for the swiveled inlet-pipe 5. A ring 6 is attached to the upperend of the pipe 4 and rests upon the upper face of the cover 3. In theupper face of the ring 6 is an annular groove 7, which is semicircularin cross-section, and in said groove operate a series of balls 8.

A flange 9 encircles the pipe 5 and is rigidly attached thereto, and aring 10 is attached at its upper edge to the outer edge of the flange 9,said ring encircling the ring 6. The flange 9 rests directly upon theballs 8, and thus is formed a ball-bearing supporting the pipe 5 Fig. 5is an enlarged de-' These mayand the mechanism carried therewith. A planView of this hearing is shown in Fig. 4.

A funnel consisting of the triangular side walls 11 and 12, the top 13,and the flaring bottom 14 is attachedto the upper end of the pipe 5. Thedischarge-opening of said funnel is at the rear of the bottom piece 14and corresponds to the upper end of the pipe 5. A shaft 15 is mountedhorizontally between the lower ends of the walls 12, and a groovedpulley 1G is mounted upon the center of said shaft. The door 17 isattached to the front edge of the bottom piece 14 and is designed toclose the outer opening of the funnel. A chain 18 is attached to saiddoor 17 and passes over the grooved pulley 16 and thence down the pipe5. A rod 19 is attached to the lower end of said chain and extends downthe inletpipe 1 and terminates in the ring 20.

A weather-vane 21 is attached to the top of the top piece 13. Below theceilings 22 of each room to be ventilatedinlet-pipes 23 are tapped intothe vertical pipe 1. These pipes 23 extend horizontally from the pipe 1to near the side walls 24 of'the'rooms and then are bent downwardly andextend to a point near the floors of said rooms and terminate in theinverted funnels or flared openings 25.

Trap-doors 26 are hinged to the inner ends of the pipes 23and aredesigned to close said pipes. The trap-doors 26 operate in theinlet-pipe 1. Arms 27 are attached to the doors 2G, and rods 28 passoutwardly through the wall of the pipe 1 and are designed to be used formanipulating the trap-doors 26, as required, to regulate the passage ofair from the inlet-pipe 1 into the pipes 23.

Outlet-pipes 29, similar to the pipes 23, are tapped into theoutlet-pipe 2 at the opposite side from the pipes 23 and extendoutwardly in a horizontal line near the under side of the ceilings to apoint near the walls of said room and thence downwardly partly to the InFig. 5 is shown an enlarged view of the lower end of the pipe 29, thetrap-door being shown open in dotted'lines and closed in full lines.

The cover 3 upon the upper end of the inlet-pipe 1 extends in ahorizontal line over the pipe 2, and triangular pieces and 34 areattached to said cover 3 and project downwardly and are attached to theupper end of the outlet-pipe 2. The side of the pipe 2 which comesbetween the side pieces 33 and 34 is cut away, thus forming afunnel-shaped discharge-opening for said pipe 2.

A trap-door 35 is hinged to the wall of the pipe 2 opposite the cutawayportion just mentioned and is designed to close the upper end of thepipe 2. A retraetile coil-spring 3G is attached to the underside of thecover 3 and to the upper side of the trap-door 35 and is designed tohold said trap-door open. A rod 37, terminating in the ring 38, isattached at its upper end to the under side of the trapdoor 35 andextends down the pipe 2 through the bottom of said pipe and is designedas a means of opening and closing said trap-door. A small opening 30 ispositioned in the wall bet-ween the inlet-pipe 1 and the outlet-pipe 2and near the upperend of said outlet-pipe.

In the practical operation of my improved ventilating system the actionof the wind upon the weather-vane 21 will keep the inlet-funnel faein gthe wind and the force of said wind will be concentrated by striking thewalls 1.1 and 12 and the upper face of the door 17, and will be directeddown the inlet-pipe 5 and down the inlet'pipe 1, thence through the pipe2 and out through the discharge-opening. The circulation of the air iscontrolled by the operation of the rods 28 opening and closing andregulating the trap-doors 26, and by the operation of the rod19 openingand closing the trap-door 17, and by the operation of the rod 37 openingand closing the trap-door 35, and by opening and closing the trap-doors30.

My improved ventilating system is simple and inexpensive inconstruction, easy of operation, and possesses many advantages over' thedevices heretofore in use for the same purpose.

I claim 1. In a ventilating system, a funnel consisting of thetriangular side walls 11 and 12, the top 13 and the flaring bottom 14,the pipe 5 attached to and forming the dischargeopening for said funnel,the trap-door 17 hinged to the front edge of the bottom piece 14 and ofsuch length as to form an extension of the funnel when lowered and closethe funnel when lifted, and means of operating said trap-door,substantially as specified.

2. In a ventilating system, a swiveled funnel, a trap-door hinged to thelower outer edge of said funnel and of such a length as to form anextension of the funnel when said trap-door is lowered and to close saidfunnel when the same is lifted, and means of operating said trap-door,substantially as specified.

3. In a ventilating system, a funnel, atrapdoor hinged to the lowerouter edge of said funnel and of such a length as to form an extensionof the funnel when said trap-door is lowered and to close said funnelwhen the same is lifted, a pipe positioned vertically through theceiling and roof of the building, a swiveled connection between theupper end of said pipe and said funnel, a handle operating below thelower end of said pipe, and a suitable connection between said handlethrough said pipe with said trap-door, whereby said trapdoor may beoperated by manually engaging said handle, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE T. FINAGIN.
